Windows 8.1 definitely seems to be doing some automatic display scaling here, as has been rumored based on beta builds of the OS. In both Windows 8.1 and the preview of Windows Server 2012 R2, as long as a proper graphics driver was installed, Windows would automatically scale the Kirabook's screen to around 150 percent.

Dive into the manual settings and you'll find a few things that weren't here before. If the "Let me choose one scaling level for all my displays" box is checked, you'll see the same old percentage-based scaling options as before. Whatever percentage you choose will be universally applied through the entire operating system on all of your displays.
